Product Overview

What Diamond Core Bits and Countersinks Is For

Diamond Core Bits and Countersinks is the whole of the Drill Bits and Countersink category, so specification work happens inside the item rather than by picking between siblings.

Use Guide

  1. Confirm the fit

    Check diameter, bore and segment dimensions against the table above and against your machine.

  2. Set the parameters

    Start at the machine builder's figures for your material, then adjust feed until the cut runs quiet and the surface stays clean.

  3. Keep it free-cutting

    If the tool stops cutting and the face goes shiny, it has glazed. Dress it, then tell us — that means the bond should change.

  4. Order by Item ID

    Quote this product name and your machine on repeat orders.
